This is front and back frame base for aliexpress prusa i3 from http://goo.gl/45e9sw the P802-D1.dwg is what their CS gave to me P802-D2.dwg is what i made with D1 as a sample for all the hole for the smooth and threaded rods anyone can drop a reply here if you want the plastic parts I will upload the complete frame soon after i finish edit it. The seller told me that the acrylic frame is their top secret when i request them for the files LOL the printer working great, but their acrylic frame is not a quality acrylic cause after few month you will notice the acrylic will bend even my gt2 belt for y axis didnt tighten enough. and their melzi board we can't even use update firmware, just stuck with their firmware. I recommend anyone who want to purchase their 3d printer better find other prusa i3 kit from aliexpress cause there got store that sale i3 kit that come with controller that we can upload firmware into it, and maybe there no top secret about their frame LOL Edit: Upload stock fan mount, feed block, X-axis motor and idler Thanks to psyhlo for sharing more stl for this printer.
